A Manchester United player has reportedly described Ole Gunnar Solskjaer's training methods as "so basic".
There have been reports of trouble brewing in the camp following the Red Devils' 6-1 defeat to Tottenham Hotspur prior to the latest international break.
As United prepare for a trip to Newcastle United, Solskjaer is under immense pressure to get a positive result, considering their poor start to the season.
However, according to the Independent, there are a number of players who are becoming tired of the Norwegian's training methods.
It is claimed that an unnamed player had spoken to a friend and explained that the "training is so basic" and "lacking in creativity", and that the manager is feeling "insecure" due to the pressure of late.
It is believed that Solskjaer still has Ed Woodward's confidence, but the executive vice-chairman could have his hands forced if positive results don't arrive.
Earlier this week, in fact, it was claimed that the club has been sounding out a potential move for former Spurs boss Mauricio Pochettino if things don't improve.
